This month at Walgreens, small Purell Jelly Wrap Hand Sanitizers are buy one get one 50% off. Find these in the travel size section of the store. Buy two and use a $1.00/2 printable Purell coupon to pay $0.77 each! If the little Purell bottles aren’t marked buy one get one 50% off at your store, ask a cashier for a price check. I find that my stores sometimes forget to tag the travel section with monthly sales.
Note: Regular prices can vary by store.
